Introduction: SFX is a self contained sound capsule for model trains and requires no connections because it is battery powered and uses a motion sensor to detect whether it is stationary or moving and a microprocessor to play appropriate real train sounds! No on-off switch is required because it turns itself on automatically as soon as it moves, then switches off after it has been still for a while to save battery. These are the sounds you can expect to hear from your SFX10. They are not simulated effects but real sounds recorded by us on the North Norfolk Railway from Steam loco B12 8572 except the coaling shoveling which is from Oliver Cromwell 70013. • Resting – Gentle steam hiss plus a Pump and occasional Fireman coaling • Any movement triggers the sound of steam release and if motion continues there is a short whistle followed by ‘chuffs’ • Steam chuffs get gradually faster as speed builds and then coasts with a steam hiss for a while before the “chuffs” return • A double whistle sounds if the loco travels continuously for a while • When motion stops it returns to Resting sounds. • When there is no motion for around a minute the SFX automatically goes to sleep and waits for movement to wake it up.
